Second point: own-justification certainty is not held as firm as faith that Christ is God's Son
Not all Reformed doctors teach that each believer must be as firmly sure of personal justification and eternal salvation as of the dogma that Christ is God's Son and the world's Redeemer — so calling that common consent is false accusation.
Many Reformed already grant that own-salvation persuasion can be separated from faith for a long time and belongs only to faith's accidental perfection — so it cannot bind with the same firmness as the Christ-article, which no one can lose even briefly and still remain truly faithful.
Latin
CXXXIII. Nec minus evidenter probare possum non omnes Scholae Reformatae Doctores sentire & docere, quod singuli fideles tam firmiter & certo persuasi esse debeant se esse justos coram Deo, & sibi esse remissa peccata, adeoque salutis aeternae se fore compotes; quam certo credere tenentur Christum esse Dei filium, & mundi Redemptorem, & similia fidei Christianae dogmata: ac per consequens falsum & calumniosum esse, si quis dicat a Reformatis istud communi consensu doceri. Et primo quidem ex eo quod plurimi ex Reformatis, sicut jam ostensum est, agnoscunt talem persuasionem de propria salute, & remissione peccatorum suorum, posse saltem ad longum tempus, a fide separari, & non esse fidei salvificae essentialem, sed ad perfectionem ejus accidentalem solummodo pertinere, ex eo, inquam, manifeste sequitur, juxta eorum sententiam, id fidelibus tam firmiter persuasum esse non debere, quam hoc quod Jesus Christus sit Dei filius, & mundi Redemptor. Nam certa persuasio de hoc articulo non potest a vera fide separari: neque potest aliquis ea persuasione ad tempus destitui, & tamen vere fidelis manere, secundum receptam & omnibus probatam Scholae Reformatae doctrinam.
